Suiteroom Number 1

Suiteroom Number 1 (スイートルームナンバー１) is the full-length debut album by v-u-den, the Hello! Project-associated Japanese pop trio led by former Morning Musume and Tanpopo member Rika Ishikawa. Meant to commemorate the band's first anniversary as a unit, the release date actually came 13 months after the release of their first single. It contains all five of the band's single A-sides — "Koi no Nukegara", "Kacchoiize! JAPAN", "Ajisai Ai Ai Monogatari", "Hitorjime", and "Kurenai no Kisetsu" — plus several songs (and two opening and closing skits) centered on the "hotel room" concept of the album.

The album caps a prolific year for Ishikawa, who in the 13 months between V-u-den's first single and the release of the album, had also recorded three final singles and one last studio album (Ai no Dai 6 Kan) with Morning Musume, done one-off singles with fellow Morning Musume member Sayumi Michishige under the name Ecomoni, and with Maki Goto, Natsumi Abe and Aya Matsuura under the name DEF.DIVA, and became the de facto host of Hello! Project's Japanese TV show Hello! Morning. This activity may have had something to do with the lengthy wait for V-u-den's first full-length album to see the light of day.
